Lab 1: Introduction to SPSS You must attend your registered lab. A Lab Results Sheet will be given to you at the beginning of your registered lab (and not before). This must be completed and handed in before you leave at the end of your registered lab. 1. Log in to the computer using your SFU computer ID and password. Your personal drive space (H:/) will automatically be mounted. 2. Download and save to your personal drive space the grip.xlsx file from the course web site. 3. Open the MS EXCEL application and use it to open the grip.xlsx file. Recommend you do not open the file by double clicking the file icon in the folder. 4. In the grip.xlsx file, modify the variable names to include units, then delete the second row of the file. e.g. Grip max Right kg becomes Grip max Right kg 5. Save the file with the new name gripnew.xlsx. 6. Open SPSS and open the same gripnew.xlsx file. 7. Save the data file in the SPSS .sav format as grip.sav 8. Go into Variable View of the SPSS Data Editor and assign the missing value 99 to each of the strength, length, girth & skinfold variables. Also assign variable labels (on next page) and value labels (where appropriate) to each variable. E.g. SEX: Sex of Subject, 1 = Man, 2 = Woman 9. Using Split File from the Data menu list, group the data for future analysis split by the SEX variable. 10. Using Compute from the Transform menu list, create a new variable which is the difference between right and left max grip strengths. Assign a variable label to this new variable. 11. Using Descriptive Statistics from the Analyze menu list, select the Descriptives option and select each of the right and left max grip strengths, hand lengths, forearm girths & forearm skinfolds for analysis (there are 8 variables total). With the split file by sex on, using the Options button on the Descriptives dialogue box select the mean, standard deviation (SD), standard error of the mean (SEM), and coefficient of skewness as the statistics to calculate. Complete the Lab Results sheet from these calculated statistics. 12. Save the grip.sav SPSS file in a safe place, for possible use later in the course.
